  • nHibernate Mapping with Oracle Varchar2 Data Types

    - by Blake Blackwell
    I am new to nHibernate and having some issues getting over the learning curve. My current question involves passing a string value as a parameter to a stored sproc. The error I get is: Input string is not in correct format. My mapping file looks like this: <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="MyCompany.MyProject.Core" namespace="MyCompany.MyProject.Core" > <class name="MyCompany.MyProject.Core.MyTable" table="My_Table" lazy="false"> <id name="Id" column="Id"></id> <property name="Name" column="Name" /> </class> <sql-query name="sp_GetTable" callable="true"> <query-param name="int_Id" type="int"/> <query-param name="vch_MyId" type="String"/> <return class="MyCompany.MyProject.Core.MyTable" /> call procedure MYPKG.MYPROC(:int_Id,:vch_MyId) </sql-query> </hibernate-mapping> When I debug nHibernate it looks like it is not an actual string value, but instead just an object value. Not sure about that though... EDIT: Adding additional code for clarification: UNIT Test List<ProcedureParameter> parms = new List<ProcedureParameter>(); parms.Add( new ProcedureParameter { ParamName = "int_Id", ParamValue = 1} ); parms.Add( new ProcedureParameter { ParamName = "vch_MyId", ParamValue = "{D18BED07-84AB-494F-A94F-6F894E284227}" } ); try { IList<MyTable> myTables = _context.GetAllByID<MyTable>( "sp_GetTable", parms ); Assert.AreNotEqual( 0, myTables.Count ); } catch( Exception ex ) { throw ex; } Data Context Method IQuery query = _session.GetNamedQuery( queryName ); foreach( ProcedureParameter parm in parms ) { query.SetParameter(parm.ParamName, "'" + parm.ParamValue + "'"); } return query.List<T>(); Come to think of it, it may have something to do with my DataContext method.

  • How to use HtmlEncode with TemplateFields, Data Binding, and a GridView

    - by Yadyn
    I have a GridView bound to an ObjectDataSource. I've got it supporting editing as well, which works just fine. However, I'd like to safely HtmlEncode text that is displayed as we do allow special characters in certain fields. This is a cinch to do with standard BoundFields, as I just set HtmlEncode to true. But in order to setup validation controls, one needs to use TemplateFields instead. How do I easily add HtmlEncoding to output this way? This is an ASP.NET 2.0 project, so I'm using the newer data binding shortcuts (e.g. Eval and Bind). What I'd like to do is something like the following: <asp:TemplateField HeaderText="Description"> <EditItemTemplate> <asp:TextBox ID="TextBoxDescription" runat="server" Text='<%# System.Web.HttpUtility.HtmlEncode(Bind("Description")) %>' ValidationGroup="EditItemGrid" MaxLength="30" /> <asp:Validator ... /> </EditItemTemplate> <ItemTemplate> <asp:Label ID="LabelDescription" runat="server" Text='<%# System.Web.HttpUtility.HtmlEncode(Eval("Description")) %>' /> </ItemTemplate> </asp:TemplateField> However, when I try it this way, I get the following error: CS0103: The name 'Bind' does not exist in the current context

  • Design approach, string table data, variables, stl memory usage

    - by howieh
    I have an old structure class like this: typedef vector<vector<string>> VARTYPE_T; which works as a single variable. This variable can hold from one value over a list to data like a table. Most values are long,double, string or double [3] for coordinates (x,y,z). I just convert them as needed. The variables are managed in a map like this : map<string,VARTYPE_T *> where the string holds the variable name. Sure, they are wrapped in classes. Also i have a tree of nodes, where each node can hold one of these variablemaps. Using VS 2008 SP1 for this, i detect a lot of memory fragmentation. Checking against the stlport, stlport seemed to be faster (20% ) and uses lesser memory (30%, for my test cases). So the question is: What is the best implementation to solve this requirement with fast an properly used memory ? Should i write an own allocator like a pool allocator. How would you do this ? Thanks in advance, Howie

  • mysql query to dynamically convert row data to columns

    - by Anirudh Goel
    I am working on a pivot table query. The schema is as follows Sno, Name, District The same name may appear in many districts eg take the sample data for example 1 Mike CA 2 Mike CA 3 Proctor JB 4 Luke MN 5 Luke MN 6 Mike CA 7 Mike LP 8 Proctor MN 9 Proctor JB 10 Proctor MN 11 Luke MN As you see i have a set of 4 distinct districts (CA, JB, MN, LP). Now i wanted to get the pivot table generated for it by mapping the name against districts Name CA JB MN LP Mike 3 0 0 1 Proctor 0 2 2 0 Luke 0 0 3 0 i wrote the following query for this select name,sum(if(District="CA",1,0)) as "CA",sum(if(District="JB",1,0)) as "JB",sum(if(District="MN",1,0)) as "MN",sum(if(District="LP",1,0)) as "LP" from district_details group by name However there is a possibility that the districts may increase, in that case i will have to manually edit the query again and add the new district to it. I want to know if there is a query which can dynamically take the names of distinct districts and run the above query. I know i can do it with a procedure and generating the script on the fly, is there any other method too? I ask so because the output of the query "select distinct(districts) from district_details" will return me a single column having district name on each row, which i will like to be transposed to the column.

  • Entity Data Model & DataGridView - Creating new objects

    - by AcousticBoom
    I'm pretty new to the EDM, so bear with me. I have a windows form that has a DataGridView on it that's bound from the EDM I created. I figured out how to update my changes fine, but it's when the user creates a new row that I'm having a problem. I tried numerous ways and many google searches, but came up with nothing so far. Here's how the data is loaded: Dim boilerID As Integer = DirectCast(ddlBoiler.SelectedValue, Integer) Dim countryID As Integer = DirectCast(ddlCountry.SelectedValue, Integer) Dim ratings = From r In _Context.Rating _ Where r.Boiler.Boiler_ID = boilerID _ And r.Country.Country_ID = countryID _ Order By r.Sequence _ Select r RatingBindingSource.DataSource = ratings.ToList() Also, all I'm doing to save the information right now is the following: Private Sub btnSave_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSave.Click _Context.SaveChanges() End Sub I want the user to be able to use the grid's "new row" feature to add new items to the database instead of having to click a button and open a new dialog. How would this be accomplished? I can include some of the methods i tried for adding new items if anyone needs to see. Thanks!

  • DataGridView not displaying data in ToolStripDropDown

    - by jblaske
    I'm utilizing the code posted by Jesper Palm here: http://stackoverflow.com/questions/280891/make-user-control-display-outside-of-form-boundry /// <summary> /// A simple popup window that can host any System.Windows.Forms.Control /// </summary> public class PopupWindow : System.Windows.Forms.ToolStripDropDown { private System.Windows.Forms.Control _content; private System.Windows.Forms.ToolStripControlHost _host; public PopupWindow(System.Windows.Forms.Control content) { //Basic setup... this.AutoSize = false; this.DoubleBuffered = true; this.ResizeRedraw = true; this._content = content; this._host = new System.Windows.Forms.ToolStripControlHost(content); //Positioning and Sizing this.MinimumSize = content.MinimumSize; this.MaximumSize = content.Size; this.Size = content.Size; content.Location = Point.Empty; //Add the host to the list this.Items.Add(this._host); } } I've translated it to VB: Public Class PopupWindow Inherits System.Windows.Forms.ToolStripDropDown Private _content As System.Windows.Forms.Control Private _host As System.Windows.Forms.ToolStripControlHost Public Sub New(ByVal content As System.Windows.Forms.Control) Me.AutoSize = False Me.DoubleBuffered = True Me.ResizeRedraw = True Me._content = content Me._host = New System.Windows.Forms.ToolStripControlHost(content) Me.MinimumSize = content.MinimumSize Me.MaximumSize = content.MaximumSize Me.Size = content.Size content.Location = Point.Empty Me.Items.Add(Me._host) End Sub End Class It works great with a PictureBox showing its information. But for some reason I cannot get the DataGridView to display anything when it is in the popup. If I pull the grid out of the popup it displays all of its information fine. If I pause during debug, the grid shows that it has all the data in it. It's just not displaying anything. Does anybody have any ideas?

  • Creating Array of settings names and values using ADO.NET Entities

    - by jordan.baucke
    I'm using an ADO.NET Entities (.edmx) data-model along with MVC2 to build an application. I have a DB table where I want to store settings for method that run elsewhere. MVC2 allows me to create a view, editor, etc. to update this table which is great, but now when I want to do simple assignments based on column titles I'm a bit confused. For example, I would like to easily build an array that I could offset into the record's value based on it's "Title" Column: var entities = new ManagerEntities(); Setting[] settings = entities.settings.ToArray(); This returns something like: Settings[0].[SettingTitle][SettingValue] However, I would like to more easily index into the value than having to loop through all the returned settings, when they're already index. string URL_ID_NEED = [NeededUrl][http://www.url.com] Am I missing something relatively simple? Thanks! ========================= *Update* ========================= Ok, I think I've got a solution, but I'm wondering why this would be so complicated, and if I'm just not thinking of the right context for ADO.NET objects, here's what I did: public string GetSetting(string SettingName) { var entities = new LabelManagerEntities(); IEnumerable<KeyValuePair<string, object>> entityKeyValues = new KeyValuePair<string, object>[] { new KeyValuePair<string, object>("SettingTitle", SettingName) }; EntityKey key = new EntityKey("LabelManagerEntities.Settings", entityKeyValues); // Get the object from the context or the persisted store by its key. Setting settingvalue = (Setting)entities.GetObjectByKey(key); return settingvalue.SettingValue.ToString(); } This method handles the job of querying the Entities by "Key" to get back the correct value as a returned string (which I can than strip out the " ", or or cast to an integer, etc. etc.,) Am I just duplicating functionality that already exists in ADO.NET's design patterns (I'm pretty new to it) -- or is this a reasonable solution?

  • UiPickerView change font color according data

    - by Fulkron
    I'm using a pickerView with multiple components related to several fields in a Database (CoreData). Is it possible to change the fontcolor for a specific component according the presence of data in the DB ? For example the field in the DB is null the component font color should be RED otherwise black. Any help will be appreciated ! Dario ================== Thanks Kenny, I have to apply to a single UIPicker only. So I', returning the view parametere (without modificatiosn). The result is all the pickers show empty rows. Thanks for help ! Here you will find the code fragment: - (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view { if (pickerView == tipoPk){ UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 100,30)]; label.textColor = [UIColor redColor]; switch (component) { case PK_Tipo: label.text = [tipoArray objectAtIndex:row]]; break; case PK_Settore: label.text = [settoreArray objectAtIndex:row]]; break; default: break; } return label; } else { return view; // <==== return view for non related pickerviews , but no rows shown } }

  • Updating Lists of Lists in Tapestry4 using textfields and a single submit button

    - by Nicolas Scarrci
    In Tapestry 4 I am trying it iterate over a list of lists (technically a list of objects who have a list of strings as a data field). I am currently doing this by using 'nested' for components. (This is pseudo code) <span jwcid="Form"> <span jwcid="@For" source="ognl:Javaclass.TopLevelList" value="ognl:SecondLevelList" index="ognl:index"> <span jwcid="@For" source="ognl:SecondLevelList.List" value="ognl:ListItem" index="ListItemIndex"> <span jwcid="@TextField" value="ognl:ListItem"/> <span jwcid="@Submit" listener="ognl:listeners.onSubmit"/> </span></span></span> The onSubmit listener then accesses the index and ListItem index page properties, as well as the ListItem page property in order to correctly update the list in Javaclass.TopLevelList. This works fine, but it looks terrible, and is cumbersome to the end user. I would prefer to somehow simulate this functionality using only one submit button at the bottom of the page. I have looked into somehow using the overlying form component to obtain a list of the 'form control components' within it, and then (with great care) parsing through tapestry's naming conventions to recover the functionality of the indexes. If anyone knows how to do this, or could explain the form component (how/when it submits, etc.) it would be greatly appreciated.

  • XML Attributes or Element Nodes?

    Example XML using element nodes: <?xml version="1.0" encoding="utf-8"?> <users> <user> <name>David Smith</name> <phone>0441 234443</phone> <email>[email protected]</email> <addresses> <address> <street>1 Some Street</street> <town>Toy Town</town> <country>UK</country> </address> <address> <street>5 New Street</street> <town>Lego City</town> <country>US</country> </address> </addresses> </user> </users> Example XML using attributes: <?xml version="1.0" encoding="utf-8"?> <users> <user name="David Smith" phone="0441 234443" email="[email protected]"> <addresses> <address street="1 Some Street" town="Toy Town" country="UK" /> <address street="5 New Street" town="Lego City" country="US" /> </addresses> </user> </users> I'm needing to build an XML file based on data from a relation database and can't work out whether I should use attributes or elements. What is best practice when building XML files?

  • Updating CoreData xcdatamodel file troubles - attribute type change

    - by San
    I noticed several questions related to this topic go unanswered. Is this such a gray area that nobody really understands it? Here is my problem: I am a midway in the development of my app and the app has never been used ouside of my iphone simulator.One of the attributes in my core data structure requires a type change.Since my app has never been used outside of my iPhone Simulator, I first deleted the sqlite file. Doubling the effort of this step, I also went into iPhone Simulator menu and selected "Reset Content and Settings...". Than, I edited the xcdatamodel file and changed the type of my attribute. I saved the file and exited. Without any other changes, I compiled. I expected it to fail because of my type change. It did not! After this, I assigned a value with new type to my attribute and it fails to compile?! Is there something else that I need to do for the change to take an effect? I would really, really appreciate an answer to my question. Thank you!

  • Good grammar for date data type for recursive descent parser LL(1)

    - by Totophil
    I'm building a custom expression parser and evaluator for production enviroment to provide a limited DSL to the users. The parser itself as the DSL, need to be simple. The parser is going to be built in an exotic language that doesn't support dynamic expression parsing nor has any parser generator tools available. My decision is to go for recursive descent approach with LL(1) grammar, so that even programmers with no previous experience in evaluating expression could quickly learn how the code works. It has to handle mixed expressions made up of several data types: decimals, percentages, strings and dates. And dates in the format of dd/mm/yyyy are easy to confuse with a string of devision ops. Is where a good solution to this problem? My own solution that is aimed at keeping the parser simple involves prefixing dates with a special symbol, let's say apostrophe: <date> ::= <apostr><digit><digit>/<digit><digit>/<digit><digit><digit><digit> <apostr> ::= ' <digit> ::= '0'..'9'

  • Data Binding to an object in C#

    - by Allen
    Objective-c/cocoa offers a form of binding where a control's properties (ie text in a textbox) can be bound to the property of an object. I am trying to duplicate this functionality in C# w/ .Net 3.5. I have created the following very simple class in the file MyClass.cs: class MyClass { private string myName; public string MyName { get { return myName; } set { myName = value; } } public MyClass() { myName = "Allen"; } } I also created a simple form with 1 textbox and 1 button. I init'd one instance of Myclass inside the form code and built the project. Using the DataSource Wizard in Vs2008, i selected to create a data source based on object, and selected the MyClass assembly. This created a datasource entity. I changed the databinding of the textbox to this datasource; however, the expected result (that the textbox's contents would be "allen") was not achieved. Further, putting text into the textbox is not updating the name property of the object. I know i'm missing something fundamental here. At some point i should have to tie my instance of the MyClass class that i initialized inside the form code to the textbox, but that hasn't occurred. Everything i've looked at online seems to gloss over using DataBinding with an object (or i'm missing the mark entirely), so any help is great appreciated. ----Edit--- Utilizing what i learned by the answers, i looked at the code generated by Visual Studio, it had the following: this.myClassBindingSource.DataSource = typeof(BindingTest.MyClass); if i comment that out and substitute : this.myClassBindingSource.DataSource = new MyClass(); i get the expected behavior. Why is the default code generated by VS like it is? Assuming this is more correct than the method that works, how should i modify my code to work within the bounds of what VS generated?

  • NSFetchedResultsController not updating UITableView's section indexes

    - by Luther Baker
    I am populating a UITableViewController with an NSFetchedResultsController with results creating sections that populate section headers and a section index. I am using the following method to populate the section index: - (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView { return [fetchedResultsController_ sectionIndexTitles]; } and now I've run into a problem. When I add a new element to the NSManagedObjectContext associated with the NSFetchedResultsController, the new element is saved and appropriately displayed as a cell in the UITableView ... except for one thing. If the new element creates a new SECTION, the new section index does not show up in the right hand margin unless I pop the UINavigationController's stack and reload the UITableViewController. I have conformed to the NSFetchedResultsControllerDelegate's interface and manually invoke [self.tableView reloadSectionIndexTitles]; at the end of both these delegate methods: controller:didChangeSection... controller:didChangeObject... and while I can debug and trace the execution into the methods and see the reload call invoked, the UITableView's section index never reflects the section changes. Again, the data shows up - new sections are physically visible (or removed) in the UITableView but the section indexes are not updated. Am I missing something?

  • Migration for creating and deleting model in South

    I've created a model and created initial migration for it: db.create_table('tvguide_tvguide', ( ('id', models.AutoField(primary_key=True)), ('date', models.DateField(_('Date'), auto_now=True, db_index=True)), )) db.send_create_signal('tvguide', ['TVGuide']) models = { 'tvguide.tvguide': { 'channels': ('models.ManyToManyField', ["orm['tvguide.Channel']"], {'through': "'ChannelInTVGuide'"}), 'date': ('models.DateField', ["_('Date')"], {'auto_now': 'True', 'db_index': 'True'}), 'id': ('models.AutoField', [], {'primary_key': 'True'}) } } complete_apps = ['tvguide'] Now, I'd like to drop it: db.drop_table('tvguide_tvguide') However, I have also deleted corresponding model.

  • Databinding in WinForms performing async data import

    - by burnside
    I have a scenario where I have a collection of objects bound to a datagrid in winforms. If a user drags and drops an item on to the grid, I need to add a placeholder row into the grid and kick off a lengthy async import process. I need to communicate the status of the async import process back to the UI, updating the row in the grid and have the UI remain responsive to allow the user to edit the other rows. What's the best practice for doing this? My current solution is: binding a thread safe implementation of BindingList to the grid, filled with the objects that are displayed as rows in the grid. When a user drags and drops an item on to the grid, I create a new object containing the sparse info obtained from the dropped item and add that to the BindingList, disabling the editing of that row. I then fire off a separate thread to do the import, passing it the newly bound object I have just created to fill with data. The import process, periodically sets the status of the object and fires an event which is subscribed to by the UI telling it to refresh the grid to see the new properties on the object. Should I be passing the same object that is bound to the grid to the import process thread to operate on, or should I be creating a copy and merging back the changes to the object on the UI thread using BeginInvoke? Any problems or advice with this implementation? Thanks

  • Status of Data in Rollback of Large Transaction in SQL Server

    - by Lloyd Banks
    I have a data warehousing procedure that downloads and replaces dozens of tables from a linked server to a local database. Every once in a while, the code will get stuck on one of the tables on the linked server because the table on the linked server is in a state of transition. I am under the assumption that since the entire procedure is considered one transaction commit, when the procedure gets stuck, none of the changes made by the procudure so far would have committed. But the opposite seems to be true, tables that were "downloaded" before the procedure got stuck would have been updated with today's versions on the local server. Shouldn't SQL Server wait for the entire procedure to finish before the changes are durable? CREATE PROCEDURE MYIMPORT AS BEGIN SET NOCOUNT ON IF EXISTS (SELECT * FROM INFORMATION.SCHEMA.TABLES WHERE TABLE_NAME = 'TABLE1') DROP TABLE TABLE1 SELECT COLUMN1, COLUMN2, COLUMN3 INTO TABLE1 FROM OPENQUERY(MYLINK, 'SELECT COLUMN1, COLUMN2, COLUMN3 FROM TABLE1') IF EXISTS (SELECT * FROM INFORMATION.SCHEMA.TABLES WHERE TABLE_NAME = 'TABLE2') DROP TABLE TABLE2 SELECT COLUMN1, COLUMN2, COLUMN3 INTO TABLE2 FROM OPENQUERY(MYLINK, 'SELECT COLUMN1, COLUMN2, COLUMN3 FROM TABLE2') --IF THE PROCEDURE GETS STUCK HERE, THEN CHANGES TO TABLE1 WOULD HAVE BEEN MADE ON THE LOCAL SERVER WHILE NO CHANGES WOULD HAVE BEEN MADE TO TABLE3 ON THE LOCAL SERVER IF EXISTS (SELECT * FROM INFORMATION.SCHEMA.TABLES WHERE TABLE_NAME = 'TABLE3') DROP TABLE TABLE3 SELECT COLUMN1, COLUMN2, COLUMN3 INTO TABLE3 FROM OPENQUERY(MYLINK, 'SELECT COLUMN1, COLUMN2, COLUMN3 FROM TABLE3') END

  • Silverlight 3 - Data Binding Position of a rectangle on a canvas

    - by Blounty
    Hi Everyone, I am currently trying to bind a collection of objects to a Canvas in Silverlight 3 using an ItemsControl as below: <ItemsControl x:Name="ctrl" ItemsSource="{Binding myObjectsCollection}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <Canvas></Canvas> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemTemplate> <DataTemplate> <Rectangle Stroke="LightGray" Fill="Black" StrokeThickness="2" RadiusX="15" RadiusY="15" Canvas.Left="{Binding XAxis}" Height="25" Width="25"> </Rectangle> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> Unfortunately it seems the binding on the Canvas.Left is being ignored. From what i have learned here it would appear this is due to the items being placed inside a content presenter not the actual canvas i have specified in the items panel. Is there a way i can use data binding to determine the position of elements on a canvas?

  • OData / WCF Data Service - HTTP 500 Error

    - by Eric
    I have created an OData/WCF service using Visual Studio 2010 on Windows XP SP3 with all current patches installed. When I click on "view in browser", the service opens and I see the 3 tables from my EF model. However, when I add a table name ("Commands" in this case) to the end of the query string, rather than seeing the data from the table, I get an HTTP 500 error. (This error (HTTP 500 Internal Server Error) means that the website you are visiting had a server problem which prevented the webpage from displaying.). I have not only followed the examples from 2 sites, but have also tried running the sample application that the blog poster sent me (that works on his machine), and still am not having any luck. The blog post is at Exposing OData from an Entity Framework Model Does anyone have an idea why this is occurring and how to resolve it? Here is the output of the "View in Browser": <?xml version="1.0" encoding="utf-8" standalone="yes" ?> - <service xml:base="http://localhost:1883/VistaDBCommandService.svc/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:app="http://www.w3.org/2007/app" xmlns="http://www.w3.org/2007/app"> - <workspace> <atom:title>Default</atom:title> - <collection href="Commands"> <atom:title>Commands</atom:title> </collection> - <collection href="Databases"> <atom:title>Databases</atom:title> </collection> - <collection href="Statuses"> <atom:title>Statuses</atom:title> </collection> </workspace> </service> ============================= Thanks, Eric

  • Add KO "data-bind" attribute on $(document).ready

    - by M.Babcock
    Preface I've rarely ever been a JS developer and this is my first attempt at doing something with Knockout.js. The question to follow likely illustrates both points. Backgound I have a fairly complex MVC3 application that I'm trying to get to work with KO (v2.0.0.0). My MVC app is designed to generically control which fields appear in the view (and how they are added to the view). It makes use of partial views to decide what to draw in the view based on the user's permissions (If the user is in group A then show control A, if the user in group B then show control B or possibly if the user is in group A don't include the control at all). Also, my model is very flat so I'm not sure the built-in ability to apply my ViewModel to a specific portion of the view will help. My solution to this problem is to provide an action in my controller that responds with an object in JSON format with that contains the JQuery selector and the content to assign to the "data-bind" attribute and bind the ViewModel to the View in the $(document).ready event using the values provided. Failed Proof-of-concept My first attempt at proving that this works doesn't actually seem to work, and by "doesn't work" I mean it just doesn't bind the values at all (as can be seen in this jsfiddle). I've tried it with the applyBindings inside of the ready event and not, but it doesn't seem to make any bit of difference. Question What am I doing wrong? Or is this just not something that can work with KO (though I've seen at least one example online doing the same thing and it supposedly works)? Like I said in the preface, I've only ever pretended to be a JS developer (though I've generally gotten it to work in the past) so I'm at a loss where to start trying to figure out what I'm doing wrong. Hopefully this isn't a real noob question.
